"Great job by Deniz and his hard working men. I had to go to work when they started but my retired next door neighbor watched them and told me they worked almost non- stop on a very hot 93 degree day. I would highly recommend Deniz to anyone looking for high quality roof work."

"Excellent work! Quickly responded to our roof repair call, we had a leak over our extension. Had him totally rip out and replace roofing, re-install skylights and apply sealant all around. He also fixed existing problems with the sidings. He did such an excellent job that we also hired him to replace 4 windows and redo our existing deck. He is such a hard worker and always cleans up the work area each work day. He will also be doing our chimney work as well. Highly recommended!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."
